Harvard University in Cambridge, Massachusetts, on December 12, 2023. Brian Snyder/Reuters New York CNN â The co-chair of a newly established task force dedicated to combating antisemitism at Harvard University has resigned after just a month in the position. Harvard Business School professor Raffaella Sadun's sudden departure, announced on Sunday, is a setback for the university's efforts to address antisemitism. Harvard's interim president, Alan Garber, has appointed a new co-chair for the task force as Sadun has decided to focus on her research, teaching, and administrative responsibilities at the Business School. Despite her resignation, Sadun's contributions to shaping the task force's goals have been acknowledged by Garber and she has expressed gratitude for the opportunity to combat antisemitism at Harvard. The reasons for her quick departure are unclear. Harvard is facing scrutiny from various parties, with Jewish alumni conducting an audit to identify instances of antisemitism at the university. This audit was reported by the Boston Globe and follows the resignation of Rabbi David Wolpe from a separate Antisemitism Advisory Group. The presidential task force on antisemitism, formed just over a month ago, has faced controversy over the selection of co-chair Derek Penslar, but he remains on the task force. The task force's membership includes students, professors, and administrators, with a separate task force also established to address anti-Muslim and anti-Arab bias at Harvard. The university is under investigation by a congressional committee and the Department of Education for allegations of discrimination and hate speech on campus.
